Question 399070: –|2x – 1| ≥ -3 im lost and confused about the first negative in front of the absolute and was wondering if some one can walk me threw it i do not want the answer just help on finding it Answer by Tatiana_Stebko(1539) (Show Source):
You can put this solution on YOUR website! –|2x–1|≥-3 divide both sides by -1
if you divide the inequality by a negative number, its sign (≥) is changed to the opposite (≤)
|2x–1|≤3
-3≤(2x–1)≤3
-3+1≤2x≤3+1
-2≤2x≤4 divide by 2 (positive number)
-1≤x≤2
Answer -1≤x≤2
